Spinal tap (lumbar puncture) to check the fluid that surrounds the brain and spinal cord

Blood tests may be done to look for specific proteins that are causing the immune attack on the nerves

Depending on the suspected cause of CIDP, other tests, such as x-rays, imaging scans, and blood tests, may be done.

Treatment

The goal of treatment is to reverse the attack on the nerves. In some cases, nerves can heal and their function can be restored. In other cases, nerves are badly damaged and cannot heal, so treatment is aimed at preventing the disease from getting worse.

Which treatment is given depends on how severe the symptoms are, among other things. The most aggressive treatment is only given if you have difficulty walking or if symptoms don't allow you to care for yourself or work.

Treatments may include:

Corticosteroids to help reduce inflammation and relieve symptoms

Other medicines that suppress the immune system (for some severe cases)
